The sleeve roller chain anti-breaking warning device is characterized in that a bracket (2) is fixed on the side wall of a cantilever (6); a telescopic push rod (1) penetrates through a top plate of the bracket; the top of the telescopic push rod (1) is connected with a trigger plate (12); compression springs (3) are arranged between a nut (5) in the middle of the telescopic push rod and the top plate (2-1); the bottom of the telescopic push rod (1) is connected with a chain wheel (7) through a shaft (9); the chain wheel (7) is meshed with a sleeve roller chain (10); an optoelectronic switch (13) is fixed at the top of the cantilever (6); and the end part of the trigger plate (12) is positioned at the top of the optoelectronic switch (13). According to the sleeve roller chain anti-breaking warning device, the situation that the sleeve roller chain is broken due to the fact that when the sleeve roller chain is too long, the deflection is too large, and the sleeve roller chain has interference with other parts on the bracket can be prevented, and the safety of operators is guaranteed.
Description
Technical field
The present invention relates to mechanical field, specifically the anti-breaking warning device of a kind of bushroller chain.
Background technology
For floor type boring and milling machine, its work stability and reliability, ensures that operator safety evaluates a key factor of lathe quality.The annex kind that lathe is equipped with is a lot, and wherein whether cantilever push-button station service behaviour is reliably the key factor increasing work efficiency and ensure site operation personnel's safety.Push-button station is suspended in workpiece side by flexible cantilever, and push-button station lifting travel increases with main spindle box stroke and increases.Cantilever push-button station floor installation is at machine pillar top, and semi-girder can rotate around base, simultaneously also can along base rail linear telescopic; Flexible cantilever one end connects push-button station, the other end is walked around two flat-top sprocket wheels and is fixed on semi-girder front end, anterior flat-top sprocket wheel only does gyration, also can do horizontal shifting along semi-girder guide rail, so just achieve the lifting of push-button station while the flat-top sprocket wheel at rear portion does gyration.The rolling of rear portion flat-top sprocket wheel and rectilinear motion promote to realize by the revolution of motor drive sleeve roller chain, if flexible stroke is larger up and down to need push-button station in work, this just needs bushroller chain very long, the longer amount of deflection of bushroller chain is larger, easier with semi-girder on part interferes, bushroller chain revolution transmission can be hindered time serious, cause breaking bushroller chain in motor driving process, not only affect production efficiency, but also can safety problem be produced.
Summary of the invention
Interfere to overcome the long and part on easy and semi-girder of existing floor type boring and milling machine bushroller chain, serious time can the deficiency that ruptures of bushroller chain, the invention provides the anti-breaking warning device of a kind of bushroller chain, when the anti-breaking warning device of this bushroller chain can prevent bushroller chain long, the excessive bushroller chain fracture caused of amount of deflection, ensures operator safety.
Technical scheme of the present invention is: the anti-breaking warning device of a kind of bushroller chain, comprise cantilever, described cantilever sidewall is fixed with support, support is C shape, its side plate is connected on cantilever, top board is installed with flexible push rod, and flexible push rod top is connected with trigger board, middle part is connected with nut, and the flexible push rod outer cover between nut and top board has Compress Spring; Be connected with sprocket wheel by axle bottom described flexible push rod, sprocket wheel is meshed with bushroller chain; Described cantilever top is fixed with optoelectronic switch, and described trigger board end is positioned at optoelectronic switch top.
Described flexible push rod upper end is connected with two adjusting nuts, and described trigger board is between two adjusting nuts.
Described flexible push rod lower end is fixed with sprocket holder, and sprocket holder is installed with axle, and axle outside is connected with sprocket wheel by bearing.
Described nut top is provided with backing plate, and the upper and lower two ends of Compress Spring withstand on support and backing plate respectively.
The present invention has following beneficial effect: owing to taking such scheme, cantilever sidewall fixes a set of telescopic push rod device, cantilever top is fixed with optoelectronic switch, when bushroller chain tensioner degree is not enough, when amount of deflection is excessive, telescopic push rod device moves down under spring tension thereupon, when bushroller chain is acquired a certain degree by the sagging amount of deflection of horizontal level, the trigger board at flexible push rod top triggers optoelectronic switch, signal to main frame to report to the police, remind operating personnel to check, thus avoid bushroller chain amount of deflection excessive and rupture, make production safer.

Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of support.
In figure, 1-stretches push rod, 2-support, 3-Compress Spring, 4-backing plate, 5-nut, 6-cantilever, 7-sprocket wheel, 8-bearing, 9-axle, 10-bushroller chain, 11-nut, 12-trigger board, 13-optoelectronic switch, 14-sprocket holder, 2-1-top board, 2-2-base plate, 2-3-side plate.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
Shown in Fig. 1, Fig. 2, the anti-breaking warning device of a kind of bushroller chain, comprise cantilever 6, described cantilever 6 sidewall is fixed with support 2, support 2 is C shape, is welded by top board 2-1, side plate 2-3, base plate 2-2, and top board 2-1 and base plate 2-2 parallels, and perpendicular to side plate 2-3, support 2 entirety is connected on cantilever 6 by side plate 2-3.Through flexible push rod 1 on top board 2-1, and be matched in clearance therebetween, flexible push rod 1 be can move freely.Flexible push rod 1 top is connected with trigger board 12, and flexible push rod 1 upper end is connected with two adjusting nuts 11, and trigger board 12, between two adjusting nuts 11, can regulate the high and low position of trigger board 12 by rotating two adjusting nuts.Nut 5 is connected with in the middle part of flexible push rod 1, nut 5 top is provided with backing plate 4, flexible push rod 1 outer cover between backing plate 4 and top board 2-1 has Compress Spring 3, and namely Compress Spring about 3 two ends withstand on support 2 and backing plate 4 respectively, can be regulated the pretightning force of Compress Spring 3 by adjusting nut 5.Described flexible push rod 1 lower end is fixed with sprocket holder 14, and sprocket holder 14 is n shape, two riser is fixed with the axle 9 of horizontal direction, and axle 9 outside is connected with sprocket wheel 7 by bearing 8, and sprocket wheel 7 is free to rotate, and sprocket wheel 7 is meshed with bushroller chain 10.Described cantilever 6 top is fixed with optoelectronic switch 13, and described trigger board 12 end is positioned at optoelectronic switch 13 top, and the distance between trigger board 12 and optoelectronic switch 13 is L, by regulating the position of flexible push rod 1 top adjusting nut 11, can regulate the size of L.
Bushroller chain 10 moves, and sprocket wheel 7 rotates thereupon, and due to the expanding force of bushroller chain 10 and the elastic force of Compress Spring 3, flexible push rod 1 bearing up-down force is balanced.When bushroller chain 10 is sagging, it is descending that Compress Spring 3 promotes flexible push rod 1 by backing plate 4, nut 5, thus drive trigger board 12 descending, the distance L between reduction and optoelectronic switch 13.When bushroller chain 10 amount of deflection reaches L, flexible push rod 1 top drives trigger board 12 to move down triggering optoelectronic switch 13 and sends signal to main frame, main frame will be reported to the police, and cross pine and will interfere with cantilever and then bushroller chain is fractureed, check reason and work on after process again to prevent bushroller chain 10.
